Using PHP to Convert ASCII Character to Decimal Equivalent
Solution 1
function ascii_to_dec($str)
{
for ($i = 0, $j = strlen($str); $i < $j; $i++) {
$dec_array[] = ord($str{$i});
}
return $dec_array;
}
example usage :
$ascii ="\t";
print_r( ascii_to_dec($ascii));
returns an array
Array
(
[0] => 9
)
Solution 2
ord()
is what you need
Solution 3
ord() returns the integer ascii value of a character
chr() returns a character from an ascii value
Solution 4
Try ord.

Can someone suggest a (preferably) graceful way to convert an ASCII character to its decimal equivalent using PHP?
